This is an era when etiquette is broken and music is broken, and human lives are insignificant. It is also an era when heroes and heroes emerge side by side.
Ten years ago, there was a talented young general (Mu Wanzhou's previous life) on the border of Dayong, who was a close friend of Zhenbei Prince Siyuan. The two of them once made a vow to "keep the rivers and mountains together and return to their hometown together."
However, a sudden and unjust case of "collaboration with the enemy and treason" caused the young general's entire family to be massacred. Siyuan was jealous of the emperor because he held a large number of soldiers, and was forced to make a cruel choice between "saving his best friend" and "protecting his family" (but he was actually deceived). The young general died with hatred in the fire that filled the sky, and no bones were left.
That night, Dayong lost a famous general, and Beiyan gained a vengeful evil ghost crawling back from hell.
